Block Heater

[ClarkGriswald]

Anyone ever use the stock block heaters? I have one on my GW and since its cold as he** today I thought I would plug it in.. and it burned my fsj to the ground (Just Kiddin). Its pretty hot though, Ill see in a while if it infact heated up the block when I go to work. Are these things safe to use? do they get old and cruddy and burn up or is it wise to get a new one. hmm. always nervous about electric heating elements.

Hey Clark I used mine all last winter in my 86 GW and it works great. I had no problems at all and had heat after about 5 min of run time.

Clark,

Yank that thing off there and you'll be fine. Oops, I forgot your in MICHIGAN still and haven't yet moved to Arizona. Where it's nice and warm in the winter. Wait, the weather man sayed it's getting down to 29 deg. tonight. C c can I borrow that heater tonight? http://www.ifsja.org/ubb/frown.gif

I used to live up there and we had heaters on all our cars and never had a prob with'em. Just don't plug it into 220 volt to make it heat up faster. http://www.ifsja.org/ubb/biggrin.gif We would bring the courd into the house and plug it in when we got up in the morning instead of running'em all night. Just make sure your antfreeze is up to the task.

I cant believe that jeeps even came with 1, the jeep I have been working on, runs so hot that the snow and ice melts from the windshield down to the bumper in a matter of minutes... if it is parked in a 60 degree day and is not moving smoke comes from the intake, and when the ac is turned on more heat from the engine comes in than ac...i think its sick...

He he he.. the real reason that I tried it out today is cause ever since Ive had my GW it has had a realy small leak of coolant from the waterpump\t-cover area, and I had been filling it up with hose water during the summer which slowly diluted the coolant to barely green\mostly water. So all of a sudden winter appears as it does here and snow on the way.. So I ran outside today and drained the outside waterpipe's around my house, and tried to let out water from my radiator and pour in some antifreeze. But guess what?. No drain petcock on my radiator that I can see.. what the he** is that all about, that radiator is on its way out knowing that. Anyhoo the block heater heats the coolant and I imagine it actually circulates around in there a bit just from the convection of the water. It worked when I got in it this afternoon and started it for the first time.. It was noticeable warmed up somewhat hehe. Temp gauge was moving soon after I was goin down the road, rather than the several miles it usually takes to crack the therm open. Mabye tommorow I'll pull off the bottom hose from the rad and drain out some water and do that thing.. (raassin frassin drain)

I've don't have one on my gw but all my other vehicles I've owned except the new ones have had them. I'm thinking about putting one on this GW. I saw one in JC Whitney that you attach to your heater core line and it actually circulates the water. I don't know if it would be any good or not. Has anyone tried these types?

Up here in Canada, block heaters are quite commonly used in the winter. The ones that plug in the casting plugs (frost plugs) in the block heat the coolant around the element only, the coolant has to circulate through the block to warm the rest of the engine up. The inline ones work better (if istalled properly), mimicking the water pump and circulating warm antifreeze through the whole system. To install them correctly one must make sure that they are below the majority of the coolant, allowing the warmer coolant to rise up into the engine and the colder coolant to fall back to the inline heater. It is not cold all the time here in Canada, the summer still gets to 90 or 100 F, so we have to be prepared for both extremes.

When were block heaters an option? Mine doesn't have one (unless it's hiding from me).

Just curious..
